N2  - In the present study we aimed to determine the prevalence of {C9ORF72} {GGGGCC} hexanucleotide expansion in our cohort of 53 frontotemporal lobar degeneration (FTLD) patients and 174 neurologically normal controls. We identified the hexanucleotide repeat, in the pathogenic range, in 4 (2 bv-frontotemporal dementia (FTD) and 2 FTD-amyotrophic lateral sclerosis ALS) out of 53 patients and 1 neurologically normal control. Interestingly, 2 of the \{C9ORF72\} expansion carriers also carried 2 novel missense mutations in \{GRN\} (Y294C) and in PSEN-2(I146V). Further, 1 of the \{C9ORF72\} expansion carriers, for whom pathology was available, showed amyloid plaques and tangles in addition to \{TAR\} (trans-activation response) DNA-binding protein (TDP)-43 pathology. In summary, our findings suggest that the hexanucleotide expansion is probably associated with ALS, FTD, or FTD-ALS and occasional comorbid conditions such as Alzheimer's disease. These findings are novel and need to be cautiously interpreted and most importantly replicated in larger numbers of samples.
